MTN protea mall

i am struggling to do a simswap and its been 2 months mind you the the simcard it is on contract which I am paying R500 on a monthly basis. The problem started when my daughter lost her phone and I phoned MTN to block both the sim and phone .Then I went to store at Protea glen mall to request for a simswap and there were 2 ladies one manager and the one that was assisting me I can tell you for free that the service I received there is bad and the manager is rude with no customer service experience they made me to call MTN to unblock the sim and I was taken from pillar to post for simswap .I was told tat i will be call till today
